UnverifiedWhen a model fails to correctly invoke retrieval tools or determines that a question does not require a search, it falls back to answering from training data, thereby exposing the knowledge cutoff issue.76% similarUnverifiedIn RAG scenarios, if retrieved documents contain errors or irrelevant content, the model will be misled and produce hallucinations—the classic 'garbage in, garbage out' problem.74% similarUnverifiedRetrieval-Augmented Generation (RAG) cannot completely eliminate hallucinations, as the model may still misinterpret retrieved documents or fill in gaps on its own when retrieval results are insufficient.74% similarUnverifiedTraditional RAG systems often suffer a significant drop in retrieval accuracy when faced with heterogeneous data.72% similar
